700 adult movie actresses have already been scanned into the database, including German stars Texas Patti and Micaela Schaefer.

But Mr Platte said the company has no plans to stop at 700 - with more porn stars scheduled to be scanned into the system soon.

'The adult movie industry has become a driving force for new technology,' he added.

The CEO does not see any ethical issues with his 'entertainment product', saying: 'It will never be able to replace real sex.'

Sociologist Sven Lewandowski of Wurzburg University said: 'It seems to me that two 'sex worlds' exist at the moment. There is the porn platform and - this is not meant in a derogatory way - everyday sex.'

In his opinion, there is no strong evidence to suggest that porn suppresses sexual appetite or in any way 'cheapens' a real intimate encounter.

Lewandowski is also sceptical about whether digital sex with VR accessories will become a growing trend.
